Electron error: Cannot find module 'envsub'

Roncham

I have the same problem. I updated using

git pull && npm run install-mm

I also ran npm install in each module, only 1 seemed to update. Rebooted and still get same error:

@raspberrypi:~/MagicMirror $ npm run start

> magicmirror@2.23.0 start
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js

App threw an error during load

Any other ideas?
Thanks

@Roncham I can only say that the npm run did not work

from the MagicMirror folder do

npm install --omit=dev

Roncham

@sdetweil said in Electron error: Cannot find module 'envsub':

npm install --omit=dev

That worked thank you!

@sdetweil (posting it in case somebody else is going to need it)

In my case, the NPM error was:

npm ERR! code EBADENGINE
npm ERR! engine Unsupported engine
npm ERR! engine Not compatible with your version of node/npm: magicmirror@2.31.0
npm ERR! notsup Not compatible with your version of node/npm: magicmirror@2.31.0
npm ERR! notsup Required: {"node":">=22.14.0"}
npm ERR! notsup Actual:   {"npm":"8.19.4","node":"v16.20.2"}

MagicMirror 2.31.0 needs at least Node 22, but through APT command, the Raspbian repos go up to 16. To solve this, I installed N, the Node version manager as an NPM module, then udpated Node that way.

$ sudo npm install -g n

added 1 package, and audited 2 packages in 2s

$ sudo n 22

  installing : node-v22.14.0
       mkdir : /usr/local/n/versions/node/22.14.0
       fetch : https://nodejs.org/dist/v22.14.0/node-v22.14.0-linux-armv7l.tar.xz
     copying : node/22.14.0
   installed : v22.14.0 (with npm 10.9.2)

Note: the node command changed location and the old location may be remembered in your current shell.
         old : /usr/bin/node
         new : /usr/local/bin/node
If "node --version" shows the old version then start a new shell, or reset the location hash with:
hash -r  (for bash, zsh, ash, dash, and ksh)
rehash   (for csh and tcsh)

$ node -v
v16.20.2
$ hash -r
$ node -v
v22.14.0

Then rerun npm run install-mm and it will work.

Hope it helps. :)

@hecaru yes, and IF you use my upgrade script, it will handle that for you…

same place as the install script
